The tensions came to a head around the time President Donald Trump delivered a politicized speech in late July to the Boy Scouts of America, an organization Tillerson once led, the officials said.

Just days earlier, Tillerson had openly disparaged the president, referring to him as a “moron,” after a July 20 meeting at the Pentagon with members of Trump’s national security team and Cabinet officials, according to three officials familiar with the incident.

On Tuesday, Trump called Tillerson’s remarks “fake news” in an interview with Forbes’ Randall Lane. Trump continued, “but if he did that, I guess we’ll have to compare IQ tests. And I can tell you who is going to win.”

This juicy little distraction was apparently irresistible to Mensa, the world’s largest association of people with very high IQs. In an unfortunate interview with the Boston Globe, spokesman Charles Brown said that “We’re happy to offer our test to anybody really who’s interested in joining our society.” Mensa also issued a press release proclaiming, “Mensa IQ Tests Abound in October — Politicians Welcome,” noting that “all brilliance is welcome” and “IQ testing can provide insight on how one’s brain processes information.”

The organization also weighed in on Trump’s medium of choice, Twitter, and Facebook:

However, Mensa’s move underlines a growing marketing and PR trend that involves reacting to Trump’s comments. More brand managers could consider the president’s words and actions fair game in the attempt to grab headlines.

When asked if any American president or Cabinet member has ever taken a Mensa admissions test before, Brown pointed out that while the group can confirm membership, it doesn’t release who’s actually taken the brain-busting exam.

“But it’s important to note that our admissions test is not the sole way to qualify for Mensa — there are hundreds of other prior-evidence tests that can qualify a member,” Brown said. “And the early success of many presidents no doubt exposed them to those types of qualifying avenues.”

The nonprofit organization is open to individuals who score within top two percent of the generation population. So, individuals like Albert Einstein and Stephen Hawking? Gotcha. We’re not so sure about Trump.
